Weighted cdf function to calculate XC95 values #'

fish.wt.cdf(datafile = datafile, ss = ss, plot = T, dogam = T,
  SampleID = "Station_Date", tag = "", sortvect = NULL, np = 61,
  nt = 25, addtrend = T, wd = getwd(), groups = c("BigHUC",
  "ECOREGL3", "WS_AREA"), xvar = "cond")

Arguments

datafile

environmental data, default = "datafile" from global environment.

ss

Species crosstabed data; default = "ss" from global environment.

plot

A boolean to choose if plot cdf and gam plots; default = T.

dogam

A booleen to choose if a gam fit is calculated; default = T.

SampleID

Site/sample id column; default = "Station_Date"

tag

Default = "".

sortvect

to provide a vector of species list so plots will be sorted according to the list; default = NULL.

np

Number of bins; default = 61.

nt

Minimum number of occurence; default = 25.

addtrend

A booleen if a trend should be added ( = ">" etc) in the output (T or F); default = T.

wd

Working directory for saving files.

groups

column names in datafile used for grouping the data; HUC (BigHUC), Ecoregion (ECOREGL3), and Watershed Area (WS_Area)

xvar

variable on which to base calculations; default = "cond"

Value

A dataframe of XC95 values and TIFF files of gam and/or cdf plots in the subdirectory "Results" of the directory specified by "wd".

Examples

# data data(dta.do) data(ss.sites) # run function (~20 seconds) dftv.do <- fish.wt.cdf(datafile = dta.do, ss = ss.sites, plot = T, dogam = T , SampleID = "Station_Date", tag = "wt", sortvect = NULL , np = 61, nt = 25, addtrend = T , wd = getwd(), groups = c("BigHUC","ECOREGL3","WS_AREA") , xvar = "cond")
